## Mix Redis Subscriber

Redis native protocol Subscriber based on Swoole coroutine

基于 Swoole 协程的 Redis 原生协议订阅库

使用 Socket 直接连接 Redis 服务器，不依赖 phpredis 扩展，该订阅器有如下优点：

- 平滑修改：可随时增加、取消订阅通道，实现无缝切换通道的需求。

- 跨协程安全关闭：可在任意时刻关闭订阅。

- 通道获取消息：该库封装风格参考 golang 语言 [go-redis](https://github.com/go-redis/redis) 库封装，通过 channel 获取订阅的消息。

## Installation

- Swoole >= 4.4

```

composer require mix/redis-subscriber

```

## 订阅频道

- 连接、订阅失败会抛出异常

```php

$sub = new \Mix\Redis\Subscriber\Subscriber('127.0.0.1', 6379, '', 5); // 连接失败将抛出异常

$sub->subscribe('foo', 'bar'); // 订阅失败将抛出异常

$chan = $sub->channel();

while (true) {

    $data = $chan->pop();

    if (empty($data)) { // 手动close与redis异常断开都会导致返回false

        if (!$sub->closed) {

            // redis异常断开处理

            var_dump('Redis connection is disconnected abnormally');

        }

        break;

    }

    var_dump($data);

}

```

接收到订阅消息：

```

object(Mix\Redis\Subscriber\Message)#8 (2) {

  ["channel"]=>

  string(2) "foo"

  ["payload"]=>

  string(4) "test"

}

```
